CoH always relied a great deal of abstraction - defeats {arrest? Kill?}, influence {cashable cool points or actual money?} and so on, so the amount of violence always depended on the eye of the beholder. What we do know is that, graphically, there's never any blood, dismemberment or anything to visually imply death, as well as the fact that, at least blueside, killing the suspect was treated as a no-no by the authorities.
As for the pitch itself, I'll just mention that the pitch included a three-page section on how it fits the "family friendly" category.
